朱雀三号回收验证火箭重复使用技术，距离地面几公里的位置，出现异常燃烧，未能实现软着陆

Core Viewpoint - The successful maiden flight of the Zhuque-3 reusable launch vehicle marks a significant milestone in China's aerospace industry, despite the failure of the first stage rocket recovery, showcasing advancements in reusable rocket technology and laying a foundation for future improvements [1][7][10]. Group 1: Flight Details - The Zhuque-3 rocket was launched on December 3, achieving a successful flight with the second stage entering orbit, while the first stage attempted a vertical recovery [3][10]. - The first stage experienced challenges during the "supersonic re-entry aerodynamic gliding phase," ultimately failing to achieve a soft landing due to an abnormal combustion during the final ignition [5][7]. Group 2: Technical Innovations - The Zhuque-3 features several domestic firsts, including the integration of a nine-engine parallel liquid oxygen-methane propulsion system and the use of stainless steel for the rocket body, which enhances durability and reusability [10][15]. - The choice of stainless steel is attributed to its strength, heat resistance, and lower material costs, making it suitable for mass production and repeated use [12][17]. Group 3: Fuel and Performance - The rocket utilizes liquid oxygen and methane as fuel, which is noted for its clean combustion and favorable cooling and ignition characteristics, making it ideal for reusable rockets [19][21]. - The current version of the Zhuque-3 has a payload capacity of approximately 13-14 tons for single use and around 10 tons for reuse, depending on the orbital requirements [14]. Group 4: Industry Context and Future Prospects - The development of reusable rockets is a global trend, driven by the need for lower launch costs and increased frequency of launches, particularly for satellite constellations [22][24]. - The Chinese government has initiated projects to develop liquid oxygen-methane reusable launch vehicles, collaborating with commercial aerospace companies to enhance technological capabilities [24][25]. - Successful recovery is just the first step; the focus will shift to ensuring the rockets can be reused effectively and economically, which is crucial for the future of the aerospace industry [27].
